我尝试执行一个不在我的Django Project目录中的python脚本...例如,这是我用命令调用的管理类:
我需要将其作为ROOT运行,因为它需要访问我的覆盆子pi上的GPIO引脚。 (我得到另一个错误)
(env) sudo python manage.py bubbles
调用此脚本:execfile(' /home/pi/rpi/bubbles.py')
# /home/pi/DjangoProjects/RaspberryPi/graphics/management/commands
from django.core.management.base import BaseCommand, CommandError
from django.core.management.base import BaseCommand
from graphics.models import Graphic
class Command(BaseCommand):
help = "My test command"
def handle(self, *args, **options):
execfile('/home/pi/rpi/bubbles.py')
我收到此错误
Traceback (most recent call last):
File "manage.py", line 8, in <module>
from django.core.management import execute_from_command_line
ImportError: No module named django.core.management
所以我猜测这是我的虚拟环境的问题,是否有办法在虚拟环境范围之外执行脚本?有没有更好的方法来使用django命令或其他方法执行此脚本。我有没有意义。
python脚本我试图打电话:
#!/usr/bin/env python
import Image
import ImageDraw
import time
from rgbmatrix import Adafruit_RGBmatrix
# Rows and chain length are both required parameters:
matrix = Adafruit_RGBmatrix(16, 2)
# Bitmap example w/graphics prims
image = Image.new("1", (16, 64)) # Can be larger than matrix if wanted!!
draw = ImageDraw.Draw(image) # Declare Draw instance before prims
# 24-bit RGB scrolling example.
# The adafruit.png image has a couple columns of black pixels at
# the right edge, so erasing after the scrolled image isn't necessary.
while True:
matrix.Clear()
image = Image.open("bubbles.png")
image.load()
for n in range(64, -image.size[0], -1):
matrix.SetImage(image.im.id, n, 1)
time.sleep(0.025)
matrix.Clear()
也许我以错误的方式解决这个问题,我只是学习将网络框架与我的树莓派合并。
答案 0 :(得分:0)
在 bubbles.py 中,而不是执行此操作
def handle(self, *args, **options):
execfile('/home/pi/rpi/bubbles.py')
试试这个
def handle(self, *args, **options):
execfile('PATH_TO_YOUR_ENV/bin/python /home/pi/rpi/bubbles.py')
